Allgemeine Beschreibung
Chromolith® NH2 columns have macropores with 2 μm diameter, giving a column efficiency exceeding 80,000 plates/meter. The mesopores are 13 nm (130 Å). Chromolith® NH2 columns fall under the USP L8 Classification. The column efficiency is comparable to a 5 μm particle size fully porous particulate column. Chromolith® NH2 columns are suitable for LC-MS applications.
The column dimension of 100 mm length and 4.6 mm I.D. is the best choice for separations of complex samples on any HPLC System.
The revolutionary, monolithic silica with its unique combination of macropores and mesopores enables:
—Rapid separations at very low column back-pressure
—High matrix tolerance, allowing time and cost savings with simplified workflows
—Cost-savings due to extended column lifetimes
—Connection of columns, flow gradients and the use of mobile phases with higher viscosity
The recommended Guard-columns are:
Chromolith® NH2 5-4.6 guard cartridges (3 pieces) [1.52030 with the Chromolith® Guard Cartridge Holder 5 mm x 4.6 mm [1.52030]
The Chromolith® column coupler can be used to significantly increase the separation efficiency of Chromolith® columns by coupling several columns in series (up to 100,000 plates/per column). [1.51467]

A new HPLC-RI method is proposed for the analysis of Lactose in milk using a Chromolith® NH2 column.
Monolithic silica HPLC columns enable high-throughput analysis at low back pressure without loss of separation efficiency or peak capacity.
This article evaluates different phase chemistries for stationary phases in Hydrophilic Interaction Liquid Chromatography (HILIC) and uses multivariate analysis for classification based on chemical modification.
